THE Cardiff rugby board has vowed to fight any legal action by the Athletic Club to stop the Blues from playing at Cardiff Arms Park.

The Athletic Club had claimed Cardiff RFC are in breach of their lease by playing as the Blues.

The board of directors, headed by chairman Peter Thomas, met for the first time since the merger collapsed and insisted they would fight their corner in a statement.

"As a board we re-iterate to all supporters that we will vigorously defend any action taken against us that would jeopardise the playing of regional and Premiership rugby at Cardiff Arms Park.

"The board unanimously agreed that there is a pressing requirement for continuing dialogue with the landlords (the Athletic Club), and as a consequence, a request is to be made for a meeting to clarify matters. We remain committed to a negotiated settlement of the current differences with our landlords.

"We firmly believe any major decision that relates to the future well being of rugby at the Arms Park is a matter for all shareholders and supporters and not for any individuals or unrepresentative bodies, including the board."

Although Celtic Warriors chief executive Leighton Samuel had dismissed the merger last week, the Blues only rejected it yesterday.

"After reviewing the commercial and political viability of such a merger, this option was unanimously rejected by the board," the statement added.

"The board is committed to strengthening and developing regional rugby through the Blues and Cardiff RFC."
